6.1Features of the IDE Controller

Primary and Secondary channels for interfacing up to four devices

IBM-AT compatible

Supports PIO and Bus Master IDE

"Ultra ATA/33/66/100" Synchronous DMA Operation

Bus Master IDE transfers up to 100 MB/sec.

Individual software control for each IDE channel

6.2Disk Drive Support

The cPB-4612 supports internal and external IDE devices. These configurations are described below.

6.2.1 Primary IDE Channel

The cPB-4612’s primary IDE channel is directed to the J14 IDE connector. J14 is used to interface with the locally mounted hard drive.

6.2.2 Secondary IDE Channel

The cPB-4612’s Secondary IDE channel is directed via the J5 rear-panel I/O connector to a compatible rear panel I/O board. Rear Panel I/O boards, such as the cRT-4612, can be installed in-line behind the cPB-4612 to provide expanded I/O capability. Refer to the DTI PlexSys cRT-4612 Packet Switched Rear- Panel Transition Board Hardware Manual for product information.

6.3IDE I/O Mapping

The I/O map for the IDE interface varies depending on the mode of operation. The default mode is "compatibility mode," meaning that the interface uses the PC-AT legacy addresses of 1F0h-1F7h, with 3F6h and interrupt IRQ14 for the primary channel. The secondary channel uses I/O addresses 170h- 177h, 376h and interrupt IRQ15. No memory addresses are used.

6.4IDE Device Drivers

The IDE interface works with all applications by default. To fully utilize the IDE interface, additional software drivers need to be installed. Contact the vendor of your intended operating system to receive the latest drivers
